[LinuxBIOS] NMI debugging tool ?

I was thinking the same ...  
even though I am aware of the fact that ROM debugging is hardly possible 
in an early state (no RAM set up yet) I still wonder about the 
feasibility of a debugger in ROM. or does it not help much more than a 
regular Linux debugging kernel and is thus hardly worth the effort ?

There is a gdb backend in LinuxBIOSv2, but I never used it.
